Cambridge Audio 651P Moving Magnet And Moving Coil Phono Pre-Amplifier - AZUR651PBLK
For true vinyl fans, a high performance phono pre-amplifier is a must-have
to get the best performance from your music. Thankfully, Cambridge Audio has
the perfect solution in the shape of the 651P. Adding weight, scale and detail
to all your favourite music, our flagship 651P, is a thoroughly reworked and
revised replacement for the legendary 640P, which picked-up dozens of awards
in its day - Click here to read some of the best ones
Many of today’s (and yesterday’s!) audio systems, from dedicated stereo amplifiers
to all-in-one systems and receivers, lack the specialist, built-in amplification
(known as a ‘phono preamp’ or ‘phono stage’) required for the direct connection
of turntables. Cambridge Audio’s 651P phono preamplifier, allows virtually all
turntables on the market to flourish by using a sophisticated electronic circuit
design that has been created to accommodate the two most commonly found types
of phono cartridge used with modern turntables: Moving Magnet (MM) and Moving
Coil (MC). Designed to bring out the hi-fi realism inherent to vinyl’s grooves,
the 651P is one of our most cost-effective, performance-enhancing creations.
The 651P uses advanced amplification circuitry to provide the lowest possible
distortion and noise. Compatible with the audiophile’s cartridge choice, Moving
Coil, the 651P model also employs high-spec multi-parallel capacitors to achieve
exceptional RIAA accuracy. In a further nod towards its audiophile credentials
the 651P features a subsonic filter to remove the unwanted and disruptive effects
of low-frequency energy. And in line with Cambridge Audio’s commitment to the
environment, the new 651P is fitted with a power switch to allow consumption
to be zeroed when not in use.
The differences between the two magnet types can create a spirited debate amongst
vinyl aficionados and you'll find plenty of opinion across the internet
Features:
- Phono pre-amplifier with moving magnet (MM) and moving coil (MC) input stages
- Discrete transistors for the all-important input stages instead of the more
common integrated circuits
- Single-ended ‘Class A’ gain stage with audiophile passive RIAA equalisation
- Multi-parallel capacitors to achieve exceptional RIAA accuracy of only 0.3dB
up to 50kHz
- Defeatable subsonic filter to eliminate very low frequency ‘rumble’, caused
by vinyl imperfections
- Eco-friendly <1W Standby power consumption
- Acoustically damped full metal chassis with thick brushed aluminium front
panel
